Morphology is a key parameter used to study the properties of galaxies hosting Active
Galactic Nuclei (AGN), their connection with AGN, and
their formation and evolution [1]}, [2]}, [3]}, [4]}, [5]}, [6]}. Morphology is one of
the fundamental parameters for understanding some of the open
questions related to the effect of AGN on their host galaxy and
vice-versa, the origin of accretion material, the triggering mechanisms
that initiate an active phase in a galaxy, the duration of nuclear active phase,
etc. Therefore, the study of the morphology of active galaxies can place
important constraints on models of supermassive black hole (SMBH)
formation and growth, as well as on the formation and evolution of
galaxies across the cosmic time [7]}, [5]}, [9]}, [10]}. It has been suggested that
AGN may play an important role in the morphological transformation of
galaxies from late- to early-types, being responsible for
quenching [11]}, [3]}, [4]}, [5]}, [9]}, but also enhancing
[16]}, [17]} star formation. The dependence
of the environment on AGN host galaxies in combination with morphology has
been extensively studied to better understand the AGN triggering
mechanisms. It has been suggested that minor and major
mergers do not [18]}, [19]} and do [20]}, [21]}, [22]}, [23]} contribute significantly to the nuclear activity
in galaxies. In particular, the interpretation of morphology in terms of galaxy evolution still remains a problem. Since the determination
of the morphology depends strongly on image resolution, morphological
classification in deep surveys remains difficult, especially when
dealing with faint and high redshift sources [24]}.
